De La Rosa (2-1) has posted a 2.47 ERA and 1.10 WHIP in 58 1/3 innings spread out over 15 starts during his first season in the Red Sox system. He also owns an impressive strikeout-to-walk ratio (2.44) and and K/9 rate (9.41).

Although limited innings- and pitch count-wise early on, De La Rosa has gone deeper into games of late. His June 22 outing — six innings of one-hit, shutout ball against the Toledo Mud Hens (DET) — featured seven strikeouts and was arguably his best of the season.
Carter (1-0, 4.37 ERA), meanwhile, has served as Pawtucket's closer this season after signing as a minor league free agent following the 2012 season, his seventh as a member of the White Sox organization.

The 6-foot-4, 220-pound 26-year-old has registered 13 saves for Pawtucket, using his 46 strikeouts in 33 innings to his advantage, and has been particularly sharp of late. In the last month, Carter owns a 2.84 ERA and 11.4 K/9 rate.

Former Sox farmhands Mauro Gomezand Kris Johnson, who now play in the Blue Jays and Pirates systems, respectively, will join De La Rosa and Carter on the IL squad.
